USN-4663-1: GDK-PixBuf vulnerability

8 December 2020

GDK-PixBuf could be made to hang if it opened a specially crafted file.




Melvin Kool discovered that the GDK-PixBuf library did not properly handle
certain GIF images. If an user or automated system were tricked into
opening a specially crafted GIF file, a remote attacker could use this flaw
to cause GDK-PixBuf to hang, resulting in a denial of service.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 20.10
Ubuntu 20.04

After a standard system update you need to restart your session to make all
the necessary changes.
